It interrupts faults up to 10 kA per EN 60898, which means it clears short-circuits up to that level without welding contacts or cascading upstream in a panel. The B-curve trips between 3 and 5 times rated current, so it's sized for resistive and general-purpose loads where inrush stays moderate — think lighting circuits, control transformers, or relay banks. The 2-pole version switches both phase and neutral (or two phases) in one 36 mm wide module, saving a width unit over two singles. Rated for pollution degree 3 and overvoltage category III, this MCB handles the conductive environment inside an industrial enclosure. The IP20 rating with connected conductors is standard for a DIN-rail breaker. ## Deployment context and ratings that matter Snap it onto a 35 mm DIN rail inside the control panel — the quick-assembly system means no tools for mounting, just clip and wire. The combined terminal top and bottom accept solid or stranded copper; touch protection is built in, so live parts stay covered after wiring. The 70 mm installation depth leaves room behind the breaker for busbars or wiring ducts. Temperature derating applies: the breaker is rated for full 6 A up to 55 °C ambient, then linearly derated to 95 % at 55 °C, 55 % at 70 °C, and 35 % at 75 °C. The storage range is -40 °C to 75 °C. Designed for railway applications per the product designation. The halogen-free and silicon-free construction matters for panels where outgassing during a fault could contaminate sensitive electronics.","metaTitle":"Siemens 5SY4206-6CC11 SENTRON MCB, 2P B 6A 10kA","metaDescription":"Siemens 5SY4206-6CC11 SENTRON miniature circuit breaker, 2-pole, B-curve, 6 A, 10 kA breaking capacity per EN 60898.
